  1. 16. Global Warming Induced by Oceanic Anoxic Event 1a Had a Pronounced Impact on the Early Cretaceous Terrestrial Vegetation of Southern Sweden

    University essay from Uppsala universitet/Paleobiologi

    Author : Marcos Amores; [2022]
    Keywords : palynology; spore-pollen; biostratigraphy; oceanic anoxic event 1a; high-latitude; Early Cretaceous;

    Abstract : The Mesozoic is punctuated by several rapid global warming events that are marked by the worldwide deposition of organic-rich marine sediments. These events, known as oceanic anoxic events (OAEs), are characterised by intervals where the worldwide carbon cycle suffers a disruption due to major palaeoceanographic and climatic shifts, leading to anoxic marine environments and the creation of black shales.

  3. 17. “What’s the buzz with bilberries?” – Bilberry pollinator community structure and function in relation to forest type and habitat structure

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Jacob Björnberg; [2022]
    Keywords : Biology and Life Sciences;

    Abstract : Over the last century, Swedish forests have undergone rapid land-use change due to intensification of management practices for timber production and the introduction of monocultures, which have resulted in considerable habitat loss and negative impacts to biodiversity. Insects form a significant component of forest biodiversity, yet forest-dwelling pollinators remain understudied, and little is known about how management strategies affect forest insect pollinator communities.

  4. 18. Early Life Factors and Disease Development in Childhood

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Ellen Johansson; [2022]
    Keywords : Delivery mode; C-section; breastfeeding; antibiotics; probiotics; infant; microbiota; food engineering; Medicine and Health Sciences; Biology and Life Sciences;

    Abstract : Background and Aim The aim was to investigate the effects of four early life factors – delivery mode, feeding method, probiotics, and antibiotics – on disease development in childhood. This was done by conducting a structured literature review. READ MORE

  5. 19. Pollen identification using sequencing techniques

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Bimaljeet Kaur; [2022]
    Keywords : pollen; rbcL gene; barcoding; metabarcoding; Sanger sequencing; MinION sequencing;

    Abstract : Palynology or the study of pollen, is essential understand the relationship between plants and their pollinators. Traditionally, pollen grains are identified by microscopy. The method has several shortcomings, such as being time-consuming and having low taxonomic resolution. READ MORE

  6. 20. Individual trait matching of bumblebees (Bombus) and flowers along an environmental gradient

    University essay from

    Author : Johan Per Michael Svedin; [2022]
    Keywords : Arctic climate change; Bombus; Flower morphology; Plant-pollinator trait-matching;

    Abstract : Insect pollinators serve a critical role in maintaining plant biodiversity and are especially susceptible to changes within their environment. To study the possible effects of seasonal variation in temperature, as well as climatic temperature increase on the plant-pollinator community, the relationship between bumblebee and flowering plant traits along an elevational gradient, representing warming-induced changes in plant community, were examined.
